Super Duplex S32750 / S32760 Stainless Steel | WNR 1.4410

Super Duplex S32750 also known as SAF 2507 or Super Duplex 2507. Super Duplex Stainless Steel Grade with UNS S32750 (1.4410 / 2507) is a high super duplex stainless steel with a PRE value of min.42*. Super Duplex Material, supplied by Oshwin Overseas is characterized by very good chloride corrosion resistance, combined with very high mechanical strength. Super Duplex Stainless Steel Properties (1.4410 / 2507) combines the most desirable characteristics of both ferritic and austenitic steel. Duplex 2507 or SAF 2507 is a super duplex stainless steel developed by Oshwin Overseas for applications that demand high strength and corrosion resistance. Alloy 2507 has 25% chromium (25Cr Duplex), 4% molybdenum, and 7% nickel also known as X2CrNiMoN25.7.4. This high molybdenum, chromium and nitrogen content causes high resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking. The Super Duplex Stainless Steel has undergone a number of modifications resulting in Super Duplex UNS S32750. Thus, Super Duplex S32750 must be procured only from trusted vendors like Oshwin Overseas. Super Duplex Stainless Steel also is known as Sandvik SAF 2507 / SAF 2507, is a Sandvik-owned trademark.

Oshwin Overseas manufactures Super Duplex Stainless Steel to be used in aggressive environments with properties like toughness, high strength, corrosion resistance in a large number of organic and inorganic acids. While the use of Super Duplex S32750 (1.4410 / 2507) is not recommended for exposure to temperatures more than 572F. The chemical composition of S32750 and S32760 are similar; however, the latter contains slightly more copper and tungsten. The copper content (min. 0.5, max 1.0) permits excellent resistance to corrosion in many non-oxidizing and mineral acids like hydrochloric and sulfuric acid.

Super Duplex S32750 / S32760 Stainless Steel (Super Duplex UNS S32750), manufactured by Oshwin Overseas is particularly suited for service in highly corrosive conditions and where high strength is required, in aggressive environments such as warm chlorinated seawater and acidic, chloride containing media. The properties of Super Duplex 2507 Stainless Steel (1.4410 / 2507) are being widely used in offshore oil and gas exploration and production and in heat exchanger in petrochemical and chemical processing. The Super Duplex Stainless Steel is also suitable for hydraulic and instrumentation applications in tropical marine environments. Super Duplex is listed in NACE MR 01 75 for sour service UNS S32750 and having gained ASME Approval for Pressure Vessel applications it can be used in a wide variety of applications.
